PC shipments are stagnant. According to Gartner, worldwide
PC shipments in Q2 were basically flat, declining -0.1 percent
from last year. PC shipments have grown only 5 percent since the
second quarter of 2010, when the iPad was
introduced.

Reasons for the bad numbers:

The global economy remains weak.

The upgrade cycle for business PCs has lengthened.

The iPad killed the netbook market, which had been driving
growth for the past few years.

Some Windows
loyalists are probably waiting for Windows 8 and the new
hardware form factors that will ship with it, such as
Microsoft's Surface, a touch screen tablet that doubles as a
small laptop.

Microsoft
and its PC partners have high hopes for Windows 8, which will
start shipping on new PCs in October. But for now,
the PC market sure doesn't look good.
